Has anyone ever found one louse on a
head and not found any eggs, nits or
lice. I found an adult louse in my hair Monday when doing my weekly check with my Robi comb. I proceeded to do 2 full comb outs each on my two children. Using a metal nit exterminator comb, licekiller brand products and hours of meticulous combing. I found nothing. No eggs, no lice. Next day my friend did the same comb out of my hair. (took 6 hours, My hair is shoulder length) and found nothing.
